Describe the feature you'd like

Add Dust to the MaterialType property. Lots of materials show themselves as dusts, like RFTool's Dimensional Shard, which makes them annoying to make with EE.

Could you please provide additional context to this, and maybe some screenshots if possible.
I don't know what you mean by RFTools Dim Shards are showing as dust.
Furthermore, what is the expected material behaviour if it is flagged as Dust Material Type.

RFTool's Dim Shards are tagged as Dust.
It could be used for materials just on their own as dusts, like Sawdust, for example.

In theory you can create a Material with just dust in the processedTypes. I still see no benefit in adding Dust as a Material Type.
